Only I can do a double bypass.

Did you ever have something so great that you could not hold onto. You search to replace it, you find a way to and you squeeze even tighter to hold on to the replacement only for it to slip through even faster. Each time you try again it becomes harder to hold onto. Pretty much everything you hold onto begins to have the feeling of Crisco to it. Then you are just left with slick empty hands.

No good for heart surgery.

I try to wash my hands of the whole thing. There unfortunately is blood in the water.
